0–100, higher is better. How it is calculated

Premier-stores.co.uk represents a large UK-based retail convenience store chain with over 5000 stores, focusing on serving local communities. The website provides information about their stores, special offers, and product categories such as food to go and own label products. The site is built on Drupal CMS and integrates modern technologies including Google Maps API and Cookiebot for cookie consent management. The presence of Google Analytics indicates moderate user tracking for analytics purposes. Security posture is generally good with HTTPS enforced and cookie consent mechanisms in place, though the absence of explicit security headers and WHOIS data gaps reduce overall trust slightly. The site is professional, well-branded, and optimized for mobile users, targeting general retail customers in the UK.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: mailserver.premier-stores.co.uk

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Premier operates a large network of convenience stores across the UK, positioning itself as a key player in local retail. Their business model centers on convenience retailing with a focus on community engagement and competitive special offers. The website supports customer engagement through store locators and promotional content. The company maintains active social media channels on Facebook and Twitter, enhancing customer outreach. The lack of visible direct contact details on the homepage suggests contact may be handled via dedicated pages or forms. The WHOIS data anomaly may indicate domain registration complexities but does not detract from the operational business presence.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and a comprehensive cookie consent mechanism compliant with GDPR. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options is a notable gap. No vulnerabilities or exposed sensitive data were detected in the HTML content. The WHOIS data failure is a concern for domain legitimacy verification but does not directly impact site security. Incident response and security policy information are not publicly available, indicating room for improvement in transparency. Overall, the site is secure for general users but could enhance defenses and compliance disclosures.

Recommendations

  1. Implement standard security headers (CSP, HSTS, X-Frame-Options) to strengthen browser security.
  2. Publish explicit security and incident response policies to improve transparency and trust.
  3. Provide clear and accessible contact information including company emails and phone numbers.
  4. Investigate and resolve WHOIS domain registration anomalies to improve domain legitimacy.
  5. Regularly audit third-party scripts and tracking tools for compliance and security risks.

Technical notes

Notes

The website is built on Drupal CMS, leveraging Google Maps API for store location services and Cookiebot for cookie management. The front-end uses responsive design techniques ensuring good mobile optimization and accessibility. Performance is moderate with multiple image sizes served for different devices. Google Tag Manager and Google Analytics are used for analytics and marketing tracking. The site lacks visible security headers which could be added to improve security posture. No hosting provider details were discernible from the HTML content. Overall, the technical infrastructure is modern and well-maintained but could benefit from enhanced security configurations.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
